Yes, I can speak to my own experience.
In terms of how the process was managed, in terms of the details, I would have to defer to the Privy Council Office, who are managing the process.
In terms of my own experience, I was approached and asked if I would consider having my name go forward, which I did. Since the process began, I had a couple of meetings with the office. The next meeting is with the Privy Council Office, because I will actually have to leave my position as a public servant in order to accept this position.
